Based off the long-running series of Mysterious Dungeon games by Chunsoft, this multi-title release (Red Rescue Team for the GBA, Blue Rescue Team for the DS) is an adventure game with semi-turn-based exploration of dungeons featuring characters from the Pokemon universe. It's up to the Rescue Team (Red in the GBA version, Blue in the DS version) to save Pokémon who've found themselves in trouble. While one of your goals is to figure out what exactly turned you into a Pokémon, you've also got to help Pokémon as Part of the Rescue Team. You start off serving your duties with your original partner Pokémon at your side, but as you progress, more Pokémon join the Rescue Team and become selectable.
